Softupdates give you an "insurance" that, in the event of a crash or a power outage, your filesystem will be coherent enough to be recoverable by fsck. This is the same goal as journalisation, just a different method. However, any data not fully commited to disk is forever lost. I guess this applies to unsaved documents. Note that the hard disk's write cache should be __disabled__ or there's no point in using softupdates at all. Up to now, there's no support for "safe write cache" operation. To my knowledge, it only exists in windows 2000 sp3 and xp. (it has been found ... inoperant in w2k <sp3!). hope this helps Raphael Le mercredi, 16 avr 2003, à 22:02 Europe/Zurich, David a écrit : > I have freebsd 5.0 and it uses softupdates which I hear > it is better or equal to journal filesystem.
